Detailed description

JLB090 Series bushings biggest feature is the thin-walled structure, does not occupy a large installation space. Sleeve material specially formulated high-density copper alloy strip. Compared with the traditional casting of copper, with high density, no gas shrinkage, carrying capacity, but also wear resistance, fatigue and other advantages. Bushings manufactured using advanced tooling, can be processed into a variety of engineering conditions apply oil hole, oil pit, sump friction surface strip, so that the sleeve can store a lot of grease in use, to extend the refueling interval, effective increased service life.

Application Features

1. save a lot of copper, copper sets working hours to save for car;
2. Compared with bushes to its light weight, low cost;
3. can be processed in a variety of friction surface has hole, pit, storing certain oils, prolonged refueling time is five times that of copper sets;
4. The high load capacity, especially suitable for rough friction surface;

Available forms

Straight sets, thrust washers, flanged bushings, bearings, skateboards, steel sleeve assembly.
